304 Stainless Steel Filler Rod

The lower carbon content in 304l minimizes deleterious or harmful carbide precipitation as a result of welding.

304 stainless steel filler rod.

Stainless steel filler metal options. When should i use 308l 309l or 316l filler metal. Filler rod for 304 stainless. Some er308l applications may be substituted with er309l filler metal but er316l or er316 applications generally require molybdenum and 309l contains no molybdenum.

Additionally 309 309l is recommended for welding 304 to carbon steel or for the barrier layer for overlays on carbon steel. Er308l is also one of the. 304 and type 347 for type 321. Gangsteelnewq january 16 2020 july 26 2020 en10025 4 steel plate.

Cg 12 is the cast equivalent of 309. The others should be welded with matching filler. Type 304l stainless steel type 304l stainless steel is an extra low carbon version of the 304 steel alloy. 304l can therefore be used as welded in severe corrosion environments and it eliminates the need for annealing.

To join 304 to 316 choose a 316 filler. The 316 316l types of stainless steels contain molybdenum mo and are commonly used in more corrosive applications than the 304 type. Type er347 stainless steel filler metal is ideal for er347 and er321 base materials because it matches these stabilized grades. While filler metals with 308 308l 316 and 309l designations are appropriate for welding austenitic stainless steel tube and pipe it s still important to know the attributes benefits and limitations of the specific types of filler metals within each designation.

For welding 304 to itself use a 308 308l filler metal that offers a matching chemistry. Type 347 can also be welded with type 308h filler. Type 321 is available on a limited basis as solid and cored wire. 308l including er308lsi is predominately used on austenitic stainless steels such as types 301 302 304 305 and cast alloys cf 8 and cf 3.

Unfortunately the match rule has so many exceptions that a better principle is consult a filler metal selection table for example type 304 is the most common stainless steel base material but no one offers a type 304 electrode. These filler materials are available as coated electrodes solid bare wire and cored wire. There are a lot of other stainless steel filler rods like 316l 321 and others and if you know what you are welding its best to use a match. For high temperature applications such as in the electrical power industry the high carbon 308h electrode provides better creep resistance than does 308l.

For instance when welding type 304 chrome steel a type 308 filler materials which has a barely totally different alloy content is used.
